I believe racism is in all of us, it's a part of our nature. The difference between wise and stupid people however, is that wise people know racism is a very primitive form of thinking, and they don't let it speak for them. Stupid people, on the other side, don't hold it back, simply because it's easy. It's very easy to attack someone who is different, it gives you this temporary emotion of feeling better. To realize it's cheap is a lesson we all shall learn at some point.
